[ns] ns-2.33 re-compilation error

[Waleed Tuffaha]

Hello,

I was writing an agent in ns-2.33 and it was compiling and working well.
Then I tried to recompile ns-allinone 2.33 with debugging enabled and I got
the following error:

trace/cmu-trace.o: In function `hdr_dgab_pkt::access(Packet const*)':
cmu-trace.cc:(.text._ZN12hdr_dgab_pkt6accessEPK6Packet[hdr_dgab_pkt::access(Packet
const*)]+0x7): undefined reference to `hdr_dgab_pkt::offset_'
collect2: ld returned 1 exit status
make: *** [ns] Error 1

Note that the same code didn't give any errors when I was compiling the
ns-2.33  directory only, but when I ran ./install in the ns-allinone-2.33
directory I got that error.

Does anyone know what causes this error or how to solve it ?

Thanks,
